Abstract: The rotary drum is a key component of the inverting filter centrifuge, and its design is developing towards high speed and high separation factor. Therefore, the accuracy of strength analysis of rotary drum is crucial. Based on the criteria in GB/T 28695—2012, this paper introduces the calculation methods of drum wall strength and circumferential stress inside the drum wall when the drum is rotating by taking the FWZ560 inverting filter centrifuge as an example. The allowable stress values of the material and the drum wall strength are calibrated, and the conclusion that the drum wall strength inspection is qualified is obtained, which proves that the method can meet the requirements of calculation accuracy. The calculation method described in this paper can provide reference for the development and design of this type of centrifuge.
